Abstract
A filter pack for gas and/or liquid filtration employing filter medium surfaces disposed between pairs of spacers, with the spacers having a corrugated configuration and the edges of the corrugations of each spacer preferably being mutually parallel to one another, the improvement wherein the edges of the corrugations of the spacers placed adjacent to the two sides of one filter medium surface are locally oriented at an angle toward one another.
Claims9
In a filter pack for fluid filtration, comprising means defining filter medium surfaces forming a folded filter medium and a plurality of spacers, with each surface having two sides and being disposed between a respective pair of the spacers and wherein each spacer has two connecting edges and a corrugated configuration, the improvement wherein:
- the corrugations of each respective pair of spacers adjacent the two sides of one filter medium surface are locally oriented at an angle toward one another;
- respective pluralities of the corrugations of each of the spacers of each respective pair of spacers intersect the respective two connecting edges;
- and
- each spacer and the connecting edges thereof are disposed on a same side of one of the filter medium surfaces in contact therewith and the connecting edges have a straight uncorrugated termination terminating on said same side.
In a filter pack for fluid filtration, comprising a housing and means in the housing defining filter medium surfaces forming a folded filter medium and a plurality of spacers, with each surface having two sides and being disposed between a respective pair of the spacers and wherein each spacer has two connecting edges and a corrugated configuration, the improvement wherein:
- the corrugations of each respective pair of spacers adjacent the two sides of one filter medium surface are locally oriented at an angle toward one another;
- a plurality of the corrugations of each of the spacers of each said respective pair of spacers intersects each of the two connecting edges;
- the connecting edges of each spacer have a straight uncorrugated termination;
- and
- the filter pack further comprises glue penetrating between all of the spacers and filter medium surfaces and tightly sealing the straight uncorrugated termination of the connecting edges of each spacer to said housing.
